The spacing wonky, there's not a lot of symmetry, and it's already associated with overly-cheerful children's stuff and basically no graphic designer who wants to be taken seriously goes near Comic Sans.
That being said, I'm sure it can be used tastefully; I just haven't seen any such examples myself.
